Two Crucial Android Bugs Open Door to RCE

Google has addressed two important flaws in its hottest month to month Android update that permit distant code execution (RCE) on Android mobile units.

The significant bugs (CVE-2020-0117 and CVE-2020-8597) exist in the Android System space, and would permit a remote attacker working with a specially crafted transmission to execute arbitrary code inside the context of a privileged approach. They affect Android versions 8 to Android 10.

“Successful exploitation of the most severe of these vulnerabilities could enable for remote code execution in the context of a privileged procedure,” according to a connected advisory from the Multi-State Data Sharing and Examination Middle (MS-ISAC), sent by means of e mail. “These vulnerabilities could be exploited through various strategies these kinds of as email, world-wide-web browsing and MMS when processing media files.”

Based on the privileges involved with the software, an attacker could then put in systems watch, transform or delete knowledge or develop new accounts with entire person legal rights.

The other flaws impacting System are two large-severity information and facts-disclosure difficulties affecting Android 10 (CVE-2020-0116 and CVE-2020-0119) – and Google offered no technical aspects on them.

The June stability updates also address significant-severity bugs in other regions, together with the Android Framework. These incorporate an elevation-of-privilege (EoP) bug (CVE-2020-0114) in Android 10 that “could allow a local malicious software to bypass person interaction demands in purchase to gain accessibility to added permissions,” in accordance to the security bulletin, issued on Monday.

In the meantime, Google also patched CVE-2020-0115, an EoP bug in Android 8 to Android 10 and CVE-2020-0121, an information and facts-disclosure bug in Android 10.

There are also two patches for the Android Media Framework, like CVE-2020-0118, which could permit a community malicious application to bypass user conversation requirements in get to get entry to added permissions it affects Android 10. The other is an information disclosure bug (CVE-2020-0113) influencing Android 9 and 10.

And lastly, there are three higher-severity security bugs in Android’s kernel parts. The most significant of them (CVE-2020-8647) could permit a regional attacker working with a specially crafted application to execute arbitrary code inside the context of a privileged course of action. The other two (CVE-2020-8648 and CVE-2020-8428) are also detailed as superior-severity.

Google also updated the advisories for two older bugs: CVE-2019-2219, influencing Framework for Android 8 to Android 10, could enable a nearby malicious application to bypass working process protections that isolate application information from other programs and an EoP vulnerability in Process (CVE-2019-9460) could enable a remote attacker to bypass user interaction necessities in get to achieve entry to additional permissions.

In all, June is a reasonably mild regular bulletin past month’s Android updates dealt with 39 vulnerabilities.

There ended up also patches issued this week to address numerous vulnerabilities in Qualcomm closed-source and common components utilised in Android devices.

Two of the bugs are critical and can be remotely exploited they both exist in the information-modem place of Qualcomm’s cell chips.

The flaw tracked as CVE-2019-14073 arises for the reason that the process buffers duplicate devoid of checking the dimension of the input in the modem facts, according to Qualcomm’s advisory.

“Copying [real-time transport protocol control protocol] RTCP messages into the output buffer without the need of examining the destination buffer dimension which could guide to a distant stack overflow when processing significant information or non-standard suggestions messages,” in accordance to the silicon-maker.

Also, CVE-2019-14080 stems from improper validation of the array index in the modem details, acquiring to do with ability transmission in the chipset:

“Out of certain produce can happen thanks to lack of check out of array index price although parsing [session description protocol] SDP attribute for [specific absorption rate] SAR,” Qualcomm claimed.
